Above average job. That's good isn't it? Assuming new owners will on average be... average, why the wish to get out of above average?
Because it's not enough. Above average got us into the top six over 23 grinding years. It is hitting a brick wall, as Conte, Mourinho, and Poch before him all identified the need to behave differently, 'like a big club', if we want to challenge for things.
We don't do that, we have never done that, and it does not look like we will do that. Even now, the way we act just does not match that model - we are rarely decisive when it matters, getting players in the manager wants, early, without faffing about negotiating for cheapo loans and 50p until the last seconds of the window.
It's not a fear of the unknown for me. It's a realisation that the unknown will also have a lot of potential downsides. You say you "choose to believe that we can too". We can choose to believe that, but I think a sober look at both potential upsides and downsides is warranted, not just a choice to believe.
Contrary to popular belief, a sober look at upsides and downsides is what I am basing this on. ENIC took over 23 years ago, when the football landscape was incomparably different to today and running Tottenham on a Mr.Byrite-derived 'zero in, zero out' model of slow, grinding growth was enough to lift us to UEFA Cup footie and the occasional CL appearance. It may even be that they imagined that it would lead us to more if we waited long enough for the slow growth to pay dividends.
The problem for them is, football did not obediently wait for their 25-year plan to pan out - Chelsea got taken over and zoomed past us, and then City got taken over and zoomed past us. In the late 2000s/early 2010s, it looked like Hicks and Gillett's mismanagement had opened a gap between us and Liverpool, but then FSG came in and blew ENIC away with how they ran their club - ironically relying on a lot of talent ENIC had initially identified (Edwards, Inglethorpe, etc.) to help their rise. That period when we were competing for the same players in the mid-2010s (epitomized by us turning down Sadio Mane because of his wages and going for Georges Kevin N'Koudou instead, while Liverpool just pulled the trigger) was the sliding doors moment there.
Then Josh Kroenke took over from his dad at Arsenal and started spending heavily to back Arteta. Then the Saudis took over at Saudi Sportswashing Machine and have kickstarted their rise. Now Boehly has bought Chelsea and is spending another 1.5bn on players, which will inevitably push them back past us again.
ENIC, to their credit, belatedly recognized the inadequacy of their ownership model and ploughed in about 100m last summer to keep us competitive. But as Conte pointed out (and is still pointing out), that is no longer sufficient - 60m players are needed every window if we really want to reach that next level.
ENIC are incapable of that, and have fallen back into their bad habits, if the torturous penny-pinching on Porro is any indicator.
That's why they're utterly inadequate. And as for the risks involved with a takeover, like I said, I think the risks are minimized both because of some innate advantages to being in our position (London club, meaning lots of exposure/media by default), but also our attractiveness as a brand being based heavily on our tangibles (stadium, training ground, real estate position in Haringey). IMO, Boehly wanting to buy us before he bought Chelsea is an indicator of the kind of serious buyer we can expect (or QSI), as opposed to fly-by-night types like Moshiri. Ironically enough, ENIC are in part to thank for that.
